Popovich called Zirin, who said he had never heard the Spurs coach so tense with anger.

Pop started off by giving Zirin context for his comments, stating as he has before his disappointment with the president. Popovich specifically noted that Trump’s claim that Obama did not call Gold Star families “is so beyond the pale, I almost don’t have the words.”

Popovich then offered a clear-throated rebuke of the president and those who work for him, calling Trump a “soulless coward,” a “pathological liar,” and “unfit intellectually, emotionally, and psychologically to hold this office.”

Of those who work under the president, Popovich said they are all aware of how unfit Trump is and that that, “This is their shame most of all.”
